The tricky part is, the group-supporting fediverse software and the microblogging software need to improve how they interact for this to be as good as it could be.

Right now Mastodon barely supports group users/actors/accounts, however they’re called, translating stuff from Lemmy’s format in a rather clunky way. Meanwhile Lemmy also has to roughly translate Mastodon’s format to its own, working pretty well all things considering, but leaving clear artifacts (subject line/first line repeating, community mention remaining shown, etc.).
